Bought a 180 gal tonight, noticed a small wet patch on the stand near the back when we were moving it and he said it was the filter hose that had been leaking, I even said "I hope that's not from the tank leaking" and he guaranteed me it was watertight, I believed him because we picked the tank up from his shop.. Got it home, filled it up and sure enough it's leaking at that exact spot! Can I get away with just resealing the part that's leaking or will the whole tank need done? Really annoyed because it took me 5 hours to empty my other two tanks, move fish and clean/set up the new tank!
